WEBB, OF CHARLOTTE, NORTH CAROLINA, ASSIGNOR OF ONE-FOURTHTO 'W. G. J'ARRELL MACHINE COMPANY, OF CHARLOTTE, NORTH CAROLINAEXERCISING AND VIBRATING DEVICE Application filed June 30,

My invention relates to an exercising device which is so designed as tosimulate the motions of a horse while traveling the various gaits andspeeds so as toiimpart to the rider exercise approaching that receivedfrom i horseback riding.

It is an object of my invention to provide an exercising device of thetype known as a mechanical horse, which can be so adjusted as to imitatevarious gaits of a horse, such as trotting, pacing, single-foot,galloping, etc.

Another object of my invention is to provide an exercising device havinga plurality of transversely disposedvshafts therein, together with meansfor eccentrically mounting a plurality of upstanding members on saidshafts, which are adapted to support in a resilient manner a bodyportion provided with a saddle, themechanism being adapted to beadjusted to impart various forms of exercise to the rider.

Some of the objects of my invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, showing a preferred embodiment of myinvention, in which Figure 1 is a side elevation of my device;

Figure 2 is a cross-sectional view taken along the line 2-2 in Figure 1.

Referring more particularly to the drawings, the numeral indicates thebase portion of my machine which is adapted to rest on any suitablesupport, such as a floor and mounted on this base portion are the Wormreduction gears 11 and 12, which have the transversely disposed shafts13 and 14 secured therein and adapted to be rotated thereby, saidreduction gears 11 and 12 being connected to each other by means of theshaft 15 and also mounted on the support 10 is the support 16 having anelectric motor 17 which has the extended shaft 18 on which there is thecone pulley 19 and on the shaft 15 there is another cone pulley 20 and abelt 21 is adapted to be placed on these two cone pulleys by means ofwhich rotary motion is imparted to the shaft 15, which in turn impartsrotary motion to the shafts 13 and 14 through the reduction worm gears11 and 12.

1928. Serial No. 289,480.

Adjustably mounted on the ends of the shafts 13 and 14 by means of theset screws 226 are the disks 22 and 22a, there being four of these disksor one disk on each end of each of the shafts. These disks have aplurality of holes as indicated by the reference numerals 23, 24, 25 and26, and in these holes are adapted to be loosely mounted the lower endsof the upwardly projecting members 27 and 28, and on the upper ends ofthe members 27 and 28, there being two of the members 27 at the rear ofthe horse and two members 28 at the front of the horse, are secured bywelding or any other suitable manner the compression springs 29 and 30,which compression springs at their upper ends are secured to a framework 31 and bolts 32 project downwardly from the frame work through thesprings and through the upper ends of the members 27' and 28. Secured onthe frame work 31 is the member 33, which has a curved upper surfacewhich is adapted to support a saddle 34, which saddle has the downwardlyprojecting strap portions 35 adapted to support the stirrups 36 on thelower end. thereof, and the forward portion of the member 33 has theslot 37 therein in which the handle member 38 is adapted to slide, saidhandle member having the handle bar 39.

Projecting upwardly from the base portion 10 is the support 40 which hasits upper end forked,as at 41 and in this forked portion the bolt 42 ismounted which is adapted to penetrate the member 38 and serve as apivotal point therefor. This member 38 extends downwardly and ispivotally connected to toggle joint 44, which in turn is pivotallyconnected to the lever 45 which is pivotally connected to the baseportion 10 as at 46, and pivotally'secured to the member 45 intermediateits ends is the member 47., which has the pins 48 and 49 projectingtherefrom which fit on both sides of the belt 21 and to the rear end ofthe member 47 is socured the tension. spring 50 which has its other endsecured to the bracket 51 which is mounted on the motor support 16. vThe purpose of the handle bar and the mechanism just described is toregulate the speed at which the shafts 13 and 14 are driven, and in theposition shown in Figure 1 the slowest motion will be obtained and theparts will be held in this position, and when it is desired to increasethe speed the handle bar 39 can be pulled backwardly by the rider whichwill move the belt forward on the cone pulleys 19 and 20 and thusincrease the speed of the revolving shafts 13 and 14. If desired, I canhave a variable speed motor and use the handle bar for adjusting thespeed of the motor to accomplish the same regulation in speed.

The worm reduction gears 11 and 12 have the broad bearing surfaces 11--awhich serves as supports for the shafts 13 and 14 and render otherbearing portions for the said shafts unnecessary.

The wires 52 load from the motor through a switch 53 located to the rearof the saddle and outwardly to a source of electric power as indicatedat 54, so that the operator can operate or start the machines whileseated in the saddle 34.

Itis evident that by adjustment. of the members 27 and 28 in varioussets of the holes 23 to 26, that various forms of motion may be impartedto the rider seated in the saddle 34. With all four of the members 27and 28 adjusted in the position shown a plain up and down and backwardand forward movement will beproduced, but it will be noted that theholes 23 have the greatest radius, the holes 26 the next greatestradius, the holes 24 the third greatest radius, and the holes 25 thesmallest radius, so that in case it should be desired to adjust one ofthe members 27 in the hole 26 and another of the members 27 in the hole23, for instance with a similar adjustment of the members 28 it is seenthat a compound rocking up and down movementand backward and forwardmovement and sidewise movement will be produced. In fact by variousadjustments between the wheels 22 and 22--a, and the members 27 and 28almost any desired combination of motions and movements may be obtained.

Attention is again directed to the disks 22 and 22a, being adjustablymounted on their respective shafts, and it is seen that by means ofadjusting these disks and also the members 27 and 28 in the variousholes 23 to 26 that the number of various movements is vention, andalthough specific terms are .em-.

ployed, they are'used in a generic and descriptive sense only, and notfor purposes of limitation, the scope of m invention being set forth inthe appended claims.

I claim:

1. In an exercising device, a base portion, two transversely disposedshafts mounted in said base portion, a longitudinally disposed shaftmounted in said base portion and having a driving connection between thesaid longitudinally disposed shaft and the trans versely disposedshafts, a cone pulley on the longitudhially disposed shaft, an electricmotor mounted in said base portion and having a cone pulley thereonmounted in a reverse direction to the first named cone pulley,

a belt extending between the said cone pulleys, a disk mounted on eachend of each of the transversely disposed shafts, upwardly projectingmembers mounted on the said disks in a pivotal manner, a plurality ofholes in each of said disks in which the upwardly projecting members areadapted to be mount ed, resilient means on the upward end of each of theupwardly projecting members, a saddle structure mounted on the upwardend of said upwardly projecting members and above the said resilientmeans, a pivoted handle member in said saddle structure, said pivotedhandle member extending downwardly in the base portion and having apivoted connection with the said belt to regulate the position of saidbelt with relation to the cone pulleys, to regulate the speed of thetransversely disposed shafts with relation to the speed of the motor. 7

2. An exercising device comprising a base portion, two transverselydisposed shafts rotatably mounted on said base portion, a longitudinallydisposed shaft, worm and gear connections between said longitudinallydisposed shaft and said transversely disposed shafts, variable drivingmeans for said shafts, a disk near each end of said transverselydisposed shafts, each of said disks having a plurality of holes thereinlocated at varying distances from the center of the disk, a standard foreach disk, means pivotally securing the lower end of each standard inone of said holes in said disks, a saddle member resiliently mounted onthe upper end of said standards, and means within reach of an occupantofsaid saddle for controlling said variable driving means.
